Millwall were put out of the cup by a very good Fulham outift, but they can take some positives from their 3-1 defeat.

Here are five things we learned:

Millwall still waiting for it to click – Harris experimented with a 3-5-2 formation in the first half and it was clear this did not work after being left exposed down the flanks time and time again. Fulham were clever in overloading these areas but I wouldn’t be a surprised to see the Lions use this formation again this season once the personnel get accustomed to the system.

Harris is capable of making big calls– admitting the formation didn’t work, Harris brought Mahlon Romeo on at half time and the effect was immediate. Millwall were getting on the ball and seemed on top until De La Torre doubled the visitors lead. Harris will have been happy with how his side adapted quickly to the change.

Lee Gregory can run for days – a thankless task up front for Gregory. With Tom Elliot having a poor first half Gregory was expected to make things happen out of nothing. Living of scraps he held the ball well and came deep to collect. Mustered the only half chance in the first half after chasing a ball over the top but will be disappointed with the tame effort at the end of it. The beacon of light for Millwall from the game.

League form is quite obviously the main concern – it was obvious this game was a chance for Millwall to take their eye off the league momentarily, and it would’ve served them well. The fight shown in Harris’ men in the second half will please the fans who were starting to question the commitment after recent poor showings.

Fulham were great first half – sometimes you need to hold your hands up and say ‘well played.’ Fulham were magnificent in the first half. They spent heavily in the summer assembling an already good squad. In André-Frank Zambo Anguissa they have a real player, he’s yet to get going properly in the Premier League but it’s only a matter of time before he does.
